1996～ 2 0 0 0年对 335份江苏省水稻主栽及区试品种进行稻瘟病、白叶枯病和纹枯病抗性鉴定。鉴定结果表明 :在被测的各种水稻类型中 ,籼稻品种对稻瘟病的抗性比粳稻好 ,而在粳稻类品种中 ,杂交粳稻对稻瘟病的抗性又略强于常规粳稻 ;粳稻品种对白叶枯病的抗性比籼稻强 ,常规稻对白叶枯病的抗性比杂交稻强 ;大部分被测水稻品种对纹枯病的抗性较差
From 1996 to 2000, 335 rice cultivars from Jiangsu Province were identified as rice blast, bacterial blight and sheath blight resistance. The results showed that indica rice varieties were more resistant to blast disease than japonica rice in all kinds of rice tested, while in japonica rice varieties, the resistance of japonica rice to rice blast was slightly stronger than that of japonica rice; The resistance to bacterial blight was stronger than that of indica rice, but the resistance to bacterial blight of conventional rice was stronger than that of hybrid rice; most of the tested rice varieties had less resistance to sheath blight
